Association between stringency of lockdown measures and emergency department visits during the COVID-19 pandemic: A Dutch multicentre study.

INTRODUCTION: The COVID-19 outbreak disrupted regular health care, including the Emergency Department (ED), and resulted in insufficient ICU capacity. Lockdown measures were taken to prevent disease spread and hospital overcrowding. Little is known about the relationship of stringency of lockdown measures on ED utilization. OBJECTIVE: This study aimed to compare the frequency and characteristics of ED visits during the COVID-19 outbreak in 2020 to 2019, and their relation to stringency of lockdown measures. MATERIAL AND METHODS: A retrospective multicentre study among five Dutch hospitals was performed. The primary outcome was the absolute number of ED visits (year 2018 and 2019 compared to 2020). Secondary outcomes were age, sex, triage category, way of transportation, referral, disposition, and treating medical specialty. The relation between stringency of lockdown measures, measured with the Oxford Stringency Index (OSI) and number and characteristics of ED visits was analysed. RESULTS: The total number of ED visits in the five hospitals in 2019 was 165,894, whereas the total number of visits in 2020 was 135,762, which was a decrease of 18.2% (range per hospital: 10.5%-30.7%). The reduction in ED visits was greater during periods of high stringency lockdown measures, as indicated by OSI. CONCLUSION: The number of ED visits in the Netherlands has significantly dropped during the first year of the COVID-19 pandemic, with a clear association between decreasing ED visits and increasing lockdown measures. The OSI could be used as an indicator in the management of ED visits during a future pandemic.

Screening for hazardous alcohol use in the Emergency Department: Comparison of phosphatidylethanol with the Alcohol Use Disorders Identification Test and the Timeline Follow-back.

BACKGROUND: Up to 15% of all visits to the Emergency Department (ED) are alcohol related. Identification of problematic alcohol use is important in this setting because it allows for intervention and prevention efforts. This study investigated the correlation between the objective phosphatidylethanol (PEth) marker and the subjective Alcohol Use Disorders Identification Test (AUDIT) and Timeline Followback Questionnaire (TLFB) as screening methods for hazardous alcohol use in the general ED population. METHODS: This prospective cohort study included 301 ED patients (57% male) who were seen in the ED and required to give a blood sample. The correlation between the values of PEth (PEth 16:0/18:1 and PEth 16:0/18:2) and the scores on the AUDIT and TLFB were analyzed using Spearman's rank correlation coefficient. Differences between risk categories of PEth and AUDIT were also examined. RESULTS: The Spearman correlation coefficients between PEth 16:0/18:1|PEth 16:0/18:2 values and the AUDIT scores were moderate (PEth 16:0/18:1: 0.67, p < 0.001; PEth 16:0/18:2: 0.67, p < 0.001). Of the patients who scored 'low risk drinking/abstinence' according to the AUDIT questionnaire, respectively 1% and 4% had PEth 16:0/18:1|PEth 16:0/18:2 values indicating excessive alcohol use, and another 10% and 12% had PEth 16:0/18:1|PEth 16:0/18:2 values indicating moderate alcohol consumption. Of the 12 (PEth 16:0/18:1) and 25 (PEth 16:0/18:2) patients with high-risk values, respectively 25% and 40% scored in the lowest risk category on the AUDIT questionnaire. Spearman correlation coefficients between PEth 16:0/18:1|PEth 16:0/18:2 values and TLFB two-week scores were high (PEth 16:0/18:1: 0.74, p < 0.001; PEth 16:0/18:2: 0.82, p < 0.001). CONCLUSIONS: AUDIT scores were moderately correlated with PEth values in the general ED population. In almost all cases where there was not a good correlation, patients had high PEth values with low AUDIT scores. We conclude that PEth identifies patients with problematic alcohol use who are missed by the AUDIT questionnaire and therefore PEth could be used as an additional screening method for hazardous alcohol use in this population.

Non-sterile gloves and dressing versus sterile gloves, dressings and drapes for suturing of traumatic wounds in the emergency department: a non-inferiority multicentre randomised controlled trial.

BACKGROUND: Patients with traumatic wounds frequently present to the ED. Literature on whether to treat these wounds sterile or non-sterile is sparse. Non-sterile treatment has the advantage of saving resources and costs, and could be of value in health settings where sterile materials are not readily available. Our objective was to compare the rate of wound infection after suturing traumatic lacerations with non-sterile gloves and dressings versus sterile gloves, dressings and drapes in the ED. We hypothesised that non-sterile gloves and dressings would be non-inferior to sterile gloves, dressings and drapes. The non-inferiority margin was set at 2%. METHODS: A multicentre single-blinded randomised controlled trial testing for non-inferiority of non-sterile gloves and dressings versus sterile gloves, dressings and drapes for suturing of traumatic wounds was performed in 3 EDs in The Netherlands. Adults with uncomplicated wounds were included from July 2012 to December 2016. At the time of treatment, patient and wound characteristics and management were documented. The outcome was wound infection, which was identified during follow-up in the treating ED at 5-14 days postprocedure. RESULTS: From 2468 eligible patients, 1480 were randomised in a sterile (n=747) or non-sterile (n=733) protocol. Baseline characteristics were similar in both study arms. The observed wound infection rate in the non-sterile group was 5.7% (95% CI 4.0% to 7.5%) vs 6.8% (95% CI 5.1% to 8.8%) in the sterile group. The mean difference of the wound infection rate of the two groups was -1.1% (95% CI -3.7% to 1.5%). CONCLUSION: Although recruitment ceased prior to reaching our planned sample size, the findings suggest that there is unlikely to be a large difference between the non-sterile gloves, dressings and sterile gloves, dressings and drapes for suturing of traumatic wounds in the ED.

Patient satisfaction, needs, and preferences concerning information dispensation at the emergency department: a cross-sectional observational study.

BACKGROUND: Patient satisfaction is an important indicator of emergency care quality and has been associated with information dispensation at the emergency department (ED). Optimal information dispensation could improve patient experience and expectations. Knowing what kind of information patients want to receive and the preferred way of information dispensation are essential to optimize information delivery at the ED. The purpose of this cross-sectional observational study was to evaluate patient satisfaction concerning information dispensation (including general, medical, and practical information), the need for additional information, and preferences with regard to the way of information dispensation at the ED of a teaching hospital in the Netherlands. RESULTS: Four hundred twenty-three patients (patients ≥ 18 years with Glasgow Coma Scale 15) were enrolled (response rate 79%). The median patient satisfaction score concerning the overall information dispensation at the ED was 7.5 on a rating scale 0-10. Shorter length of ED stay was associated with higher patient satisfaction in multivariate analysis (P < 0.001). The majority of respondents were satisfied regarding medical (n = 328; 78%) and general information (n = 233; 55%). Patients were less satisfied regarding practical information (n = 180; 43%). Respondents who indicated that they received general, medical and practical information were significantly more often satisfied compared to patients who did not receive this information (P < 0.001). Two thirds (n = 260; 62%) requested more general information. Half of the respondents (n = 202; 48%) requested more practical information and a third (n = 152; 36%) requested more medical information. The preferred way for receiving information was orally (n = 189; 44.7%) or by leaflets (n = 108; 25.5%). CONCLUSION: The majority of respondents were satisfied concerning information dispensation at the ED, especially regarding medical information. Respondents requested more general and practical information and preferred to receive the information orally or by leaflets.

The Effect of Written and Video Discharge Instructions After Mild Traumatic Brain Injury on Healthcare Costs and Productivity Costs.

OBJECTIVE: To compare healthcare and productivity costs between patients with mild traumatic brain injury (mTBI) who received verbal discharge instructions only and patients who received an additional flyer with or without video instructions. SETTING: Emergency departments (EDs) of 6 hospitals in the Netherlands. PARTICIPANTS: In total, 1155 adult patients with mTBI (384 with verbal instructions; 771 with additional flyer with or without video instructions) were included. DESIGN: Cost study with comparison between usual care and intervention. METHODS: Medical and productivity costs up to 3 months after presentation at the ED were compared between mTBI patients with usual care and mTBI patients who received the intervention. RESULTS: Mean medical costs per mTBI patient were slightly higher for the verbal instructions-only cohort (€337 vs €315), whereas mean productivity costs were significantly higher for the flyer/video cohort (€1625 vs €899). Higher productivity costs were associated with higher working age, injury severity, and postconcussion symptoms. CONCLUSION: This study showed that the implementation of flyer (and video) discharge instructions for patients with mTBI who present at the ED increased reports of postconcussion symptoms and reduced medical costs, whereas productivity costs were found to be higher for the working population in the first 3 months after the sustained head injury.

Undetectable High-Sensitivity Troponin T as a Gatekeeper for Coronary Computed Tomography Angiography in Patients Suspected of Acute Coronary Syndrome.

OBJECTIVES: The aim of this study was to characterize the safety and efficiency of a strategy employing the limit of detection (LoD) of high-sensitivity troponin T (hs-TnT) as a gatekeeper for coronary computed tomography angiography (CCTA) in suspected acute coronary syndrome (ACS) patients in the emergency department (ED). METHODS: We included suspected ACS patients who underwent CCTA and were evaluated with hs-TnT. Patients were categorized as below the LoD and at or above the LoD. The primary outcome was 30-day major adverse cardiac events (MACEs), defined as all-cause mortality, ACS, or coronary revascularization. RESULTS: The study population consisted of 177 patients (mean age 55 ± 10 years, 50.3% women), and 16 (9.0%) patients reached the primary outcome. None of the patients died, while 13 had an adjudicated diagnosis of ACS, and 3 underwent elective coronary revascularization. There were 77 patients (44%) with an hs-TnT value below the LoD (MACEs; n = 1 [1.3%]) and 100 (56%) with at or above the LoD levels (MACEs; n = 15 [15%]). None of 67 patients with an hs-TnT value below the LoD and <50% stenosis on CCTA experienced MACEs. Out of the 10 patients with an hs-TnT value below the LoD and ≥50% stenosis on CCTA, 1 patient underwent elective percutaneous coronary revascularization. In patients with an hs-TnT value at or above the LoD, 74 patients had <50% stenosis on CCTA, and 2 patients (3%) were diagnosed with myocardial infarction without obstructive coronary artery disease confirmed on invasive angiography. Thirteen (50%) patients with an hs-TnT value at or above the LoD and ≥50% stenosis on CCTA experienced MACEs (11 ACS and 2 elective percutaneous coronary revascularizations). CONCLUSION: Our findings support that implementing the LoD of hs-TnT as a gatekeeper may reduce the need for CCTA in suspected ACS patients in the ED.

Effect of Video Discharge Instructions for Patients With Mild Traumatic Brain Injury in the Emergency Department: A Randomized Controlled Trial.

STUDY OBJECTIVE: We measure the effect of video discharge instructions on postconcussion symptoms in patients with mild traumatic brain injury in the emergency department. METHODS: A multicenter randomized controlled trial was conducted in which patients with mild traumatic brain injury were randomly assigned to either intervention (verbal, written, and video discharge information) or control (verbal and written discharge information only). All patients were interviewed 1 week and 3 months from randomization. Primary outcome measure was the Rivermead Post-Concussion Symptoms Questionnaire at 3 months. Secondary outcomes were correct recall, Hospital Anxiety and Depression Scale score, health-related quality of life (12-Item Short Form Health Survey), return visits, and patient satisfaction. RESULTS: A total of 2,883 patients were assessed for eligibility, of whom 381 were included in the control group and 390 in the video intervention group. Difference in mean total Rivermead Post-Concussion Symptoms Questionnaire score between the 2 groups was 0.2 at 1 week and 0.3 at 3 months after traumatic brain injury (estimated effect -0.7; 95% confidence interval -2.1 to 0.7). There was also no difference in Hospital Anxiety and Depression Scale score, recall, 12-Item Short Form Health Survey score, return visits, and patient satisfaction between the control and intervention group. CONCLUSION: Severity of postconcussion symptoms in patients with mild traumatic brain injury did not improve by adding video information to standard care. Also, there was no difference in recall, health-related quality of life, return visits, and patient satisfaction between the control and intervention groups.

Effect of written and video discharge instructions on parental recall of information about analgesics in children: a pre/post-implementation study.

OBJECTIVE: The aim of this study was to determine whether written and video instructions improved the recall of how to use analgesics correctly in parents of children discharged following assessment in the emergency department (ED). METHODS: This was a prospective pre- and post-implementation study set in the EDs of a tertiary teaching hospital and an urban general hospital in the Netherlands. The participants were parents/carers of children under 12-years-old who had been assessed in and subsequently discharged from the ED. The pre-implementation phase involved 165 participants; the post-phase involved 174 participants. In the post-implementation phase, written instructions about correct analgesic use in children and a link to an online video were provided at discharge. Endpoints were measured using a questionnaire designed to ascertain participants' recall of how to use analgesics correctly and their patterns of use, completed 3-5 days following discharge of their child from the ED. Additionally, participants were asked about re-attending healthcare services and their satisfaction with and preferences for information about analgesic use. RESULTS: Recall of the correct use of analgesics was significantly higher in participants in the post-implementation phase compared to the pre-implementation phase [difference 29%; 95% confidence interval (CI) 19-39%]. In the post-implementation phase, participants represented to healthcare services less frequently (difference -6%; 95% CI -13-0%). Patterns of use of analgesics varied between the pre- and post-phases, with significantly more participants giving analgesics at home (difference 11%; 95% CI 1-20%). Participants in the post-implementation phase were significantly more (highly) satisfied about the analgesic advice they received compared to parents in the pre-implementation phase (difference -13; 95% CI -23% to -3%). Verbal (93%) or written instructions (83%) were the most popular choices for discharge instructions. CONCLUSION: In our study, we observed that the recall of the correct use of analgesics was increased in participants who had been given written instructions at discharge.

Patient Discharge Instructions in the Emergency Department and Their Effects on Comprehension and Recall of Discharge Instructions: A Systematic Review and Meta-analysis.

STUDY OBJECTIVE: We conduct a systematic review with meta-analysis to provide an overview of the different manners of providing discharge instructions in the emergency department (ED) and to assess their effects on comprehension and recall of the 4 domains of discharge instructions: diagnosis, treatment, follow-up, and return instructions. METHODS: We performed a systematic search in the PubMed, EMBASE, Web of Science Google Scholar, and Cochrane databases for studies published before March 15, 2018. A quality assessment of included articles was performed. Pooled proportions of correct recall by manner of providing discharge instructions were calculated. RESULTS: A total of 1,842 articles were screened, and after selection, 51 articles were included. Of the 51 included studies, 12 used verbal discharge instructions only, 30 used written discharge instructions, and 7 used video. Correct recall of verbal, written, and video discharge instructions ranged from 8% to 94%, 23% to 92%, and 54% to 89%, respectively. Meta-analysis was performed on data of 1,460 patients who received verbal information only, 3,395 patients who received written information, and 459 patients who received video information. Pooled data showed differences in correct recall, with, on average, 47% for patients who received verbal information (95% confidence interval 32.2% to 61.7%), 58% for patients who received written information (95% confidence interval 44.2% to 71.2%), and 67% for patients who received video information (95% confidence interval 57.9% to 75.7%). CONCLUSION: Communicating discharge instructions verbally to patients in the ED may not be sufficient. Although overall correct recall was not significantly higher, adding video or written information to discharge instructions showed promising results for ED patients.

Correction to: The early identification of disease progression in patients with suspected infection presenting to the emergency department: a multi-centre derivation and validation study.

In the publication of this article [1], there are two errors in contributing author affiliations. This has now been included in this correction article.

The early identification of disease progression in patients with suspected infection presenting to the emergency department: a multi-centre derivation and validation study.

BACKGROUND: There is a lack of validated tools to assess potential disease progression and hospitalisation decisions in patients presenting to the emergency department (ED) with a suspected infection. This study aimed to identify suitable blood biomarkers (MR-proADM, PCT, lactate and CRP) or clinical scores (SIRS, SOFA, qSOFA, NEWS and CRB-65) to fulfil this unmet clinical need. METHODS: An observational derivation patient cohort validated by an independent secondary analysis across nine EDs. Logistic and Cox regression, area under the receiver operating characteristic (AUROC) and Kaplan-Meier curves were used to assess performance. Disease progression was identified using a composite endpoint of 28-day mortality, ICU admission and hospitalisation > 10 days. RESULTS: One thousand one hundred seventy-five derivation and 896 validation patients were analysed with respective 28-day mortality rates of 7.1% and 5.0%, and hospitalisation rates of 77.9% and 76.2%. MR-proADM showed greatest accuracy in predicting 28-day mortality and hospitalisation requirement across both cohorts. Patient subgroups with high MR-proADM concentrations (≥ 1.54 nmol/L) and low biomarker (PCT < 0.25 ng/mL, lactate < 2.0 mmol/L or CRP < 67 mg/L) or clinical score (SOFA < 2 points, qSOFA < 2 points, NEWS < 4 points or CRB-65 < 2 points) values were characterised by a significantly longer length of hospitalisation (p < 0.001), rate of ICU admission (p < 0.001), elevated mortality risk (e.g. SOFA, qSOFA and NEWS HR [95%CI], 45.5 [10.0-207.6], 23.4 [11.1-49.3] and 32.6 [9.4-113.6], respectively) and a greater number of disease progression events (p < 0.001), compared to similar subgroups with low MR-proADM concentrations (< 1.54 nmol/L). Increased out-patient treatment across both cohorts could be facilitated using a derivation-derived MR-proADM cut-off of < 0.87 nmol/L (15.0% and 16.6%), with decreased readmission rates and no mortalities. CONCLUSIONS: In patients presenting to the ED with a suspected infection, the blood biomarker MR-proADM could most accurately identify the likelihood of further disease progression. Incorporation into an early sepsis management protocol may therefore aid rapid decision-making in order to either initiate, escalate or intensify early treatment strategies, or identify patients suitable for safe out-patient treatment.

Emergency department overcrowding: a survey among European neurotrauma centres.

BACKGROUND: ED overcrowding is an increasing problem worldwide that may negatively affect quality of care and patient outcomes. We aimed to study ED overcrowding across European centres. METHODS: Questionnaires on structure and process of care, including crowding, were distributed to 68 centres participating in a large European study on traumatic brain injury (Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury). RESULTS: Of the 65 centres included in the analysis, 32 (49%) indicated that overcrowding was a frequent problem and 28 (43%) reported that patients were placed in hallways 'multiple times a day'; 27 (41%) stated that multiple times a day, there was no bed available when a patient needed to be admitted. Ambulance diversion rarely occurred in the participating centres. CONCLUSION: Similar to reports from other parts of the world, ED crowding appears to be a considerable problem in Europe. More research is needed to determine effective ways to reduce overcrowding.

Workflow and factors associated with delay in the delivery of intra-arterial treatment for acute ischemic stroke in the MR CLEAN trial.

OBJECTIVE: The effect of intra-arterial treatment (IAT) for acute ischemic stroke is highly time-dependent. We investigated the delay of IAT and factors associated with such delay. METHODS: MR CLEAN was a randomized trial of IAT plus usual care versus usual care alone (n=500). With multivariable linear regression, we analyzed the effect of intravenous treatment, general anesthesia, off-hours and inter-hospital transfer on time to admission to the emergency department (ED) of the intervention center and time to treatment. Furthermore, we assessed compliance with a target of 75 min for time from ED to treatment, and calculated the potential absolute increase in the number of patients with a good outcome (modified Rankin Scale score ≤2) if this target had been achieved in all treated patients. RESULTS: Inter-hospital transfer prolonged time to ED by 140 min (95% CI 129 to 150) but reduced time from ED to treatment by 77 min (95% CI 64 to 91). Time from ED to treatment was increased by 19 min by general anesthesia (95% CI 5 to 33) and total time was increased by 23 min during off-hours (95% CI 6 to 40). The in-hospital target was achieved in 11.5% (22/192) of patients. Full compliance with the target time of 75 min from ED to treatment would have increased the proportion of patients with a good outcome by 7.6% (95% CI 6.7% to 8.5%). CONCLUSION: Inter-hospital transfer is an important cause of delay in the delivery of IAT and every effort should be made to avoid transfers and reduce transfer-related delay. Furthermore, in-hospital workflow should be optimized to improve functional outcome after IAT.

Attitude of patients, healthcare professionals, and noninjured lay persons towards online video instructions on mild traumatic brain injury: a cross-sectional study.

BACKGROUND: The objective of this study was to determine the attitude of patients, healthcare professionals, and noninjured lay persons towards adding a video with discharge instructions to patient care for patients with mild traumatic brain injury (MTBI). A survey was conducted at the emergency department (ED). Participants consisted of MTBI patients (n = 50), healthcare professionals (n = 50), and noninjured lay persons (n = 50). The participants viewed a video with discharge instructions on MTBI and filled out a questionnaire that measured their attitude towards the use of a video as part of discharge instructions. FINDINGS: Nearly all healthcare professionals (94%) and 70% of the noninjured lay persons considered the video to be a valuable addition to oral discharge instructions. For 84% of patients, verbal information from the doctor is of importance. And, 50% of patients would like to receive additional video discharge instructions. CONCLUSIONS: The majority of noninjured lay persons and healthcare professionals and half of the MTBI patients consider a video with discharge instructions to be a valuable addition to patient care. Video discharge instructions are a relative low-cost measure that could enhance patient care at the ED, provided that this does not compromise the personal contact between patient and healthcare professional.

Validity of the Manchester Triage System in emergency care: A prospective observational study.

OBJECTIVES: To determine the validity of the Manchester Triage System (MTS) in emergency care for the general population of patients attending the emergency department, for children and elderly, and for commonly used MTS flowcharts and discriminators across three different emergency care settings. METHODS: This was a prospective observational study in three European emergency departments. All consecutive patients attending the emergency department during a 1-year study period (2010-2012) were included. Validity of the MTS was assessed by comparing MTS urgency as determined by triage nurses with patient urgency according to a predefined 3-category reference standard as proxy for true patient urgency. RESULTS: 288,663 patients were included in the analysis. Sensitivity of the MTS in the three hospitals ranged from 0.47 (95%CI 0.44-0.49) to 0.87 (95%CI 0.85-0.90), and specificity from 0.84 (95%CI 0.84-0.84) to 0.94 (95%CI 0.94-0.94) for the triage of adult patients. In children, sensitivity ranged from 0.65 (95%CI 0.61-0.70) to 0.83 (95%CI 0.79-0.87), and specificity from 0.83 (95%CI 0.82-0.83) to 0.89 (95%CI 0.88-0.90). The diagnostic odds ratio ranged from 13.5 (95%CI 12.1-15.0) to 35.3 (95%CI 28.4-43.9) in adults and from 9.8 (95%CI 6.7-14.5) to 23.8 (95%CI 17.7-32.0) in children, and was lowest in the youngest patients in 2 out of 3 settings and in the oldest patients in all settings. Performance varied considerably between the different emergency departments. CONCLUSIONS: Validity of the MTS in emergency care is moderate to good, with lowest performance in the young and elderly patients. Future studies on the validity of triage systems should be restricted to large, multicenter studies to define modifications and improve generalizability of the findings.

Frequent users of the emergency department services in the largest academic hospital in the Netherlands: a 5-year report.

OBJECTIVE: To investigate the demographic and service characteristics, motive for consultation, and disposition of adult frequent users (FUs) of the largest academic hospital in the Netherlands over a 5-year period. PATIENTS AND METHODS: This retrospective study included all patients aged 18 years and older visiting the emergency department (ED) during a 5-year period (2009-2013). Frequent ED use was defined as having four or more visits to the ED during a year. Patient and service characteristics, motive for consultation, and disposition were explored. RESULTS: Frequent ED users represented 2% of all patients who visited the ED during 2009-2013 (8% of all ED consultations). On average, each FU visited the ED five times per year. Compared with nonfrequent users (NFUs), FUs were significantly less often self-referred, less frequently transported to the hospital by ambulance, received a lower urgency code upon arrival to the ED, and more often admitted to hospital than NFUs. Complaints related to the digestive system (19%), general complaints such as fever (18%), respiratory (10%), or cardiovascular problems (10%) were the main motive for consultations of the frequent ED users. Two percent of the FUs were serial FUs (FUs during 3 or more consecutive years). CONCLUSION: Frequent use of the ED has been depicted as inappropriate use of these services. However, our study shows that FUs consist of a relatively small number of patients and that FUs suffer from chronic, and often, severe somatic illnesses that require specialized medical care.

Procalcitonin-guided therapy for the initiation of antibiotics in the ED: a systematic review.

BACKGROUND: Procalcitonin (PCT) is a new biomarker with a higher accuracy in the diagnosis of bacterial infections. Utilization of PCT may reduce the number of unnecessary antibiotics prescribed to patients and consequently may decrease the rise in antibiotic resistance. The aim of this systematic review is to determine if a PCT-guided algorithm can safely reduce the number of antibiotics prescribed to all patients with a suspected of infection in the emergency department (ED). METHODS: MEDLINE, EMBASE, Web of Science, COCHRANE central, PubMed publisher, and Google scholar were searched. Two reviewers performed the screening independently. The QUADAS 2 tool was used to assess quality. RESULTS: In total, 1621 articles were screened. Nine articles were included in the analysis. In the 6 studies on adult patients, only patients with respiratory tract infections were investigated. In these studies, a cutoff value of 0.25 µg/L was used, and PCT-guided therapy reduced the number of prescribed antibiotics significantly. Three studies were on pediatric patients, 2 on fever without source and 1 on respiratory complaints. Procalcitonin-guided therapy did not reduce antibiotic prescription in children. Procalcitonin-guided therapy did not result in an increase in adverse events in any of the studies. DISCUSSION: Procalcitonin-guided therapy in the ED is only studied in subpopulations, where it was effective and safe in adult patients with respiratory tract infections and not effective but safe nonetheless in specific pediatric populations. Nonadherence is a significant problem in prospective PCT-guided therapy studies. There is not enough evidence to use PCT-guided therapy in a general ED population.

Higher diagnostic accuracy and cost-effectiveness using procalcitonin in the treatment of emergency medicine patients with fever (The HiTEMP study): a multicenter randomized study.

BACKGROUND: Fever is a common symptom in the emergency department(ED). Fever can be caused by bacterial infections, which are treated with antibiotics. Often, bacterial infections cannot be ruled out in the ED using standard diagnostics, and empiric antibiotic treatment is started. Procalcitonin(PCT) is a biomarker for bacterial infections, but its role in an undifferentiated ED population remains unclear. We hypothesize that PCT-guided therapy may reduce antibiotics prescription in undifferentiated febrile ED patients. The primary objectives of this study are to determine a) the efficacy, b) the safety of PCT-guided therapy, and c) the accuracy of the biomarker PCT for bacterial infections. The secondary objective is to study the cost-effectiveness of PCT-guided therapy. METHODS/DESIGN: This is a multicenter noninferiority randomized controlled trial. All adult ED patients with fever(≥38.2 °C) are randomized between standard care with and without the addition of a PCT level, after written informed consent. a) For efficacy, the reduction of patients receiving antibiotics is calculated, using a superiority analysis: differences between the PCT-guided group and control group are assessed using a Fisher's exact test, and a multivariable logistic regression analysis to account for the effects of demographic and medical variables on the percentage of febrile patients receiving antibiotics. b) Safety consists of a composite endpoint, defined as mortality, intensive care admission and ED return visit within 14 days. Noninferiority of PCT will be tested using a one-sided 95 % confidence interval for the difference in the composite safety endpoint between the PCT-guided and control groups using a noninferiority margin of 7.5 %. c) Accuracy of PCT and CRP for the diagnosis of bacterial infections will be reported, using the sensitivity, specificity, and the area under the receiver-operating-characteristic curve in the definitive diagnosis of bacterial infections. The sample size is 550 patients, which was calculated using a power analysis for all primary objectives. Enrollment of patients started in August 2014 and will last 2 years. DISCUSSION: PCT may offer a more tailor-made treatment to the individual ED patient with fever. Prospective costs analyses will reveal the economic consequences of implementing PCT-guided therapy in the ED. THIS TRIAL IS REGISTERED IN THE DUTCH TRIAL REGISTER: NTR4949.

Coronary CT Angiography for Suspected ACS in the Era of High-Sensitivity Troponins: Randomized Multicenter Study.

BACKGROUND: It is uncertain whether a diagnostic strategy supplemented by early coronary computed tomography angiography (CCTA) is superior to contemporary standard optimal care (SOC) encompassing high-sensitivity troponin assays (hs-troponins) for patients suspected of acute coronary syndrome (ACS) in the emergency department (ED). OBJECTIVES: This study assessed whether a diagnostic strategy supplemented by early CCTA improves clinical effectiveness compared with contemporary SOC. METHODS: In a prospective, open-label, multicenter, randomized trial, we enrolled patients presenting with symptoms suggestive of an ACS at the ED of 5 community and 2 university hospitals in the Netherlands. Exclusion criteria included the need for urgent cardiac catheterization and history of ACS or coronary revascularization. The primary endpoint was the number of patients identified with significant coronary artery disease requiring revascularization within 30 days. RESULTS: The study population consisted of 500 patients, of whom 236 (47%) were women (mean age 54 ± 10 years). There was no difference in the primary endpoint (22 [9%] patients underwent coronary revascularization within 30 days in the CCTA group and 17 [7%] in the SOC group [p = 0.40]). Discharge from the ED was not more frequent after CCTA (65% vs. 59%, p = 0.16), and length of stay was similar (6.3 h in both groups; p = 0.80). The CCTA group had lower direct medical costs (€337 vs. €511, p < 0.01) and less outpatient testing after the index ED visit (10 [4%] vs. 26 [10%], p < 0.01). There was no difference in incidence of undetected ACS. CONCLUSIONS: CCTA, applied early in the work-up of suspected ACS, is safe and associated with less outpatient testing and lower costs. However, in the era of hs-troponins, CCTA does not identify more patients with significant CAD requiring coronary revascularization, shorten hospital stay, or allow for more direct discharge from the ED.
